MAZDA DEVELOPS TWO BREAKTHROUGH TECHNOLOGIES IN PLASTICS RECYCLING

 MAZDA DEVELOPS TWO BREAKTHROUGH TECHNOLOGIES IN PLASTICS RECYCLING
 DETROIT, June 1 /PRNewswire/ -- As part of its ongoing efforts to design environmentally beneficial technologies, Mazda Motor Corporation has developed two new substances that can lead to a greater, more effective use of recycled plastics.
 The two new substances are a plastic composite that can be recycled repeatedly and a decomposing catalyst that will make possible the recovery of petroleum derivatives from all types of plastics, which can then be turned into usable fuels such as gasoline and kerosene.
 "We see this as an exciting breakthrough, not only for Mazda but also in the broader context of using innovation to meet the environmental challenges we face worldwide," said Yoshihiro Wada, president of Mazda Motor Corporation. "A major first step in that process has been the growing worldwide awareness of the need to recycle. Now we can begin looking into the next phase -- finding better, more effective uses for products that are recycled."
 Conventional plastic composites, known as Fiber Reinforced Plastics (FRPs), include glass or carbon fiber reinforcement. During the grinding and heating that takes place in recycling, the glass or carbon fibers are destroyed, rendering recycled conventional plastics unusable as structural materials.
 Mazda's new plastics composite combines easily recycled thermoplastic with liquid crystal polymers for reinforcement. The liquid crystal polymers are not destroyed during the recycling process because the polymer molecules re-bond after melting. This means the plastic can be recycled at least five times and used as a structural material in such potential applications as automobile frames, building materials, and in shipbuilding.
 The development of a new decomposing catalyst to recover petroleum derivatives from plastics also has significant potential as a contributor to plastic recycling. Once the petroleum is recovered, it can be re-refined into such usable fuels as gasoline and kerosene.
 Decomposing catalysts are used to break down used plastic materials into different elements, of which one of the most valuable is petroleum. Conventional catalysts, however, are ineffective when used with plastics that contain even a trace of chlorine.
 In the past that has meant separating chlorinated and non- chlorinated plastics prior to processing or using a special system to remove chlorine gas before it passes through the catalysts.
 The new catalyst developed by Mazda will work on all types of plastics in effectively breaking them down and reclaiming their petroleum components as a reusable resource. Mazda will establish a large-scale experimental laboratory this year to fully develop the potential promised by this new technology.
 Together, the new highly recyclable plastic and the decomposing catalyst can make an important, long-term difference in the global effort to address environmental problems.
